The kids from Glee have another impressive mash-up. This time, the all-girl group the Troubletones deliver a stellar performance of Destiny's Child's Survivor and Gloria Gaynor's classic I Will Survive.

Led by Troubletones stars Mercedes (Amber Riley) and Santana (Naya Rivera), the group's mash-up is from the upcoming Sectionals competition episode, airing on Dec. 6.

The Survivor/I Will Survive mash-up is just the latest hit mash-up to preview before the actual episode.

In mid-November, Fox treated Glee fans to a clip of the Troubletones performing a mash-up of Adele's hits Someone Like You and Rumour Has It. The preview clip has since received more than 8.5 million views -- the most viewed video on the official Glee VEVO channel.

The third season of Glee has been picking up steam again, thanks to these popular mash-ups.

The show is also anticipating the arrival of two big guest stars, scheduled for future episodes in 2012.

Gloria Estefan has reportedly been hired to play Santana's mother, The Hollywood Reporter confirmed earlier this week. Meanwhile, Ricky Martin has agreed to guest star as a Spanish teacher at McKinley High.

Martin teased Glee fans by taking to Twitter on Tuesday.

I hear McKinley high has an opening for a Spanish teacher... Maybe I'll apply, the singer wrote.

In its three seasons on Fox, Glee has sold more than 36 million songs on iTunes and more than 11 million albums worldwide. What's more impressive is that the show broke Elvis Presley's record for having the most Hot 100 hits back in February, Billboard reported.

Scroll down to watch the Troubletones perform a mash-up of Survivor and I Will Survive. The full Sectionals episode airs on Tuesday.
